FEATHERSTONE, OF BARKER, NEW YORK.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 773,860, dated November1, 1904.

Application filed May 19, 1904..

To all whom it may concern:

Be it known that I, JAMus W. FEATHER- STONE, a citizen of the UnitedStates, residing at Barker, in the county of Niagara and State of NewYork, have invented certain new and useful Improvements in Acetylene-GasGenerators, of which the following is a specification, reference beinghad to the accompanying drawings, forming a part hereof.

This invention relates to acetylene-gas generators. In some suchgenerators it is prefable to introduce the carbid into the generator ina pail or other container, a pail of fresh carbid being introduced inplace of the pail of consumed carbid as fast as the consumption ofcarbid may require. In these apparatuses the complete consumption ofcarbid is generally indicated by the appearance of the lights, whichbegin to grow dim as the gas from which they are supplied ceases to begenerated; but it happens oftentimes that a clogging of the pipes orsome other derangement of the apparatus operates to produce the sameefiect, so that the dimming of the lights cannot be relied upon as asafe criterion of the consumption of the contained carbid.

It will be obvious that the dismantling of the generator during thegeneration of gas in order to replenish the carbid is attended withdanger, particularly when done at night, as is often necessary, by theaid of a lighted lamp. It is accordingly one object of this invention toprovide a more reliable and safer test of the condition of the carbidwithin the generator than that furnished by the character of the lightsupplied from the generator.

Another object of the invention is to maintain the container support orholder free from water, so that a new container maybe quickly and easilyinserted without having first to pump out the apparatus.

Further objects of the invention consist in generally improving theapparatuses of the nature referred to.

The several features of the invention will be described hereinafter inconnection with the drawings, which illustrate a convenient embodimentof the same in an acetylene-gas generator, and in which Figure l is aview in central vertical section Serial No. 208,656. (No model.)

of the generator. Fig. 2 is a horizontal sectional view through thecarbid-container, and Fig. 3 is a view in perspective of thecarbidcontainer.

The outer shell or body a of the generator is preferably cylindrical inshape and has secured thereto within the same a cylindrical" receptacleor holder t to receive and support the pail of carbid 0. Between thesupporting-receptacle 6 and the outer shell there will accordingly beformed an annular space cl, into which a cylindrically-shaped hood orgasometer 6 extends, a small quantity of water being preferably providedin the annular space in order to seal the lower edge of the gasometer orhood to prevent the leakage there of the generated gas.

The carbid pail or container 0 extends above the sides of the receptacleZ) and is preferably divided into a plurality of sections by partitionsf, in all but one of which near the top are openings g, through whichcommunication between the adjacent sections is established. The water isintroduced into the first section it in any convenient way, preferablyfrom an opening z'in a cup in the center of the pail, and into whichwater is fed gradually from a supply-pipe Z, entering through the top ofthe hood, the water dropping from the end of said pipe into the cup. Thepressure or head of water, it will be understood, must be sulficient toovercome the pressure of the gas in the apparatus. It will be clear thatthe water will fill first the section it, then the adjacent sectionthrough the openings g, and so on, until the last section m is reached.hen the carbid is entirely consumed, the water entering the carbid-pailwill cease to be decomposed and will fill the pail up to an outlet 12,,which is preferably made flaring, as indicated in the drawings, toprevent its being clogged by impurities in the carbid or by lime whichmay exist in the pail. The partitions in the carbid-pail do not extendto the top of the pail, and in this way all the carbid is sure to becovered by water before it overflows through the outlet at, as justdescribed. This outlet is arranged to discharge into the annular space(Z, whereby the water which would otherwise overflow from the containeror pail into the realso preferably having a flaring opening, and

. when the water in the outer receptacle rises to this point it isdischarged therethrough.

The operation of the improved generator will be understoodi'romtheforegoing. VJ hen the carbid has been entirely consumed, thecontinuing feeding of the water into the carbid-pail will cause adischarge through the outlet-pipe a into the annular space (Z, as abovedescribed, which will in turn cause the Water in said annular space torise to the pipe 0, from which it will be discharged. In this way itwill be clear that the consumption of the carbid may be convenientlyindicated.

It will be obvious that many changes may be made in the construction ofthe generator without departing from the spirit of the invention, andaccordingly the invention is not limited to the precise form here shownand described.

I claim as my invention 1. In an acetylene-gas generator, thecombination of an outer shell, a carbid-container supported within theouter shell, means to supply water to the container, an outlet for theWater near the top of the container, and an outlet for the water in theshell.

2. In an acetylene-gas generator, the combination of an outer shell, acarbid-container, means to support the container forming a space betweenthe container and outer shell, means to supply water to the container,an outlet for the water near the top of the container discharging intosaid space, and an outlet in the shell below the outlet in thecontainer.

3. In an acetylene-gas generator, the combination of an outer shell, acarbid-container, a receptacle to receive the container forming a spacebetween itself and the outer shell, means to supply water to thecontainer, an outlet from and near the top of the container discharginginto said space and an outlet from said space through the outer shelland below the outlet from the container.

&. In an acetylene-gas generator, the combination of a cylindrical outershell, a carbidcontainer, a cylindrical receptacle within the shell forholding the container, the sides of which extend above the sides of thereceptacle,

said receptacle and shell forming an annular space, means to supplywater to the container, an outlet near the top of the containerdischarging into said annular space and an outlet from said spacethrough the shell and below the top of the receptacle.

5. In an acetylene-gas generator, the combination of an outer shell, asectional carbidcontainer having communications between the severalsections, and supported within the outer shell, means to supply water tothe container, an outlet from near the top of the container and anoutlet for the water in the shell.

6. In an acetylene-gas generator, the com bination of an outer shell, acarbid-container, partitions in said container dividing it intosections, all of said partitions except one having openings thereinwhereby water may be circulated through the sections successively, meansto support the container forming a space between the container and theouter shell, means to supply water to the first section of thecontainer, an outlet for the water near the top of the last sectiondischarging into said space, and an outlet in the shell.

7. In an acetylene-gas generator, the combination of an outer shell, acarbid-container, means to support the carbid-container forming a spacebetween the container and outer shell, a hood in said space, means tosupply water to the container, an outlet for the water near the top ofthe container discharging into said space, and an outlet in the shell.

8. In an acetylene-gas generator, the combination of a cylindrical outershell, a carbidcontainer, a cylindrical receptacle Within the shell forholding the container, the sides of which extend above the sides of thereceptacle, said receptacle and shell forming an annular space, a hoodextending within the annular space and surrounding the container, meansto supply Water to the container, an outlet from near the top of thecontainer discharging into said space, and an outlet from said spacethrough the shell below the top of the receptacle.
